During the existence of the Soviet Union, the region of Central and Eastern Europe was heavily dependent on supplies from the east. The Three Seas Initiative is supposed to change this necessity. By creating new energy connections, the twelve participating countries have the opportunity to diversify their gas sources and become independent from Russian supplies.

Prime anticipates connecting the Świnoujście LNG terminal in the Baltic Sea with the one under construction in the Adriatic Krk island. While completed, it would allow LNG to be shipped from the United States, Norway, Algeria or Qatar - just to mention a few main exporters - and enter the European energy market through a new route, crossing North-South connections beyond the region.

Following, BRUA gas pipeline would allow Caspian gas to enter Europe via Turkey, assuring an choice to Russia's monopoly on the Central European energy market. Different intended source is the gas from the Romanian offshore in the Black Sea. Its end-route location is none other than the Austrian hub which can guarantee the redistribution of natural gas throughout the whole continent.
